Abstract
An axial air motor having a plurality of cylinders disposed around the axis of rotation of an output shaft in such a manner that the direction of movement of the pistons is parallel with the output shaft. The air motor is provided with a swash plate which is rotatably mounted on the output shaft through a bearing and which is directly pressed by means of a ball which is mounted on each piston. Accordingly, the structure of the motor as a whole is simplified and the frictional resistance occurring between constituent parts can be minimized. Thus, it is possible to achieve an efficient axial air motor. Further, since a lubricant can be charged in a hole for receiving the ball in advance, it is possible to reduce the frictional resistance occurring between the ball and the swash plate even in a non-lubricated operation.
